Which violation involves no license plate light?

The correct violation pertaining to the absence of a license plate light is articulated in the California Vehicle Code as 24601 CVC. This particular code specifies the requirements for license plates, including their visibility and the necessity for illumination. Under this section, it is mandated that the rear license plate must be clearly legible at night, and if it is not adequately lit by a license plate light, it constitutes a violation.

This regulation is vital for ensuring that law enforcement and other drivers can easily read a vehicle's license plate, which is essential for safety and accountability on the roads. The requirement emphasizes the need for proper lighting to avoid potential infractions and to enhance the visibility of the vehicle’s identification.

In contrast, the other options pertain to different vehicle regulations. For instance, 5200 CVC focuses on the display of license plates and the requirement to have them attached in a specific manner. 22350 CVC addresses the maximum speed regulations, which is unrelated to vehicle lighting. Similarly, 4000(a)(1) CVC deals with unregistered vehicles, not specifically with the lighting or visibility of license plates. Thus, 24601 CVC is the only option that directly relates to the requirement of having a functioning license plate light.
